Save money – and more. Installing ENERGY STAR certified windows and doors lowers energy costs. With more efficient windows, you also use less energy, which reduces greenhouse gas emissions from power plants. For typical homes, choose ENERGY STAR and save on average $101 – $538 and 1,006 to 6,205 pounds of CO2 which is an equivalent to 51 to 317 gallons of gasoline a year when replacing single-pane windows.
Get comfortable. Say goodbye to cold drafts and overheated spaces. ENERGY STAR certified windows and doors help keep your home’s temperature consistently comfortable. Even relaxing on your love seat right by the window can be cozy with ENERGY STAR.
Protect your valuables. Many ENERGY STAR certified windows and doors have a special coating on the glass that is like sunscreen for your house.
